PHOTOGRAPHlC-PRINTING APPARATUS.

Specification of Letters Patent.

Patented Feb. 19, 1907.

Application filed October 31, 1906. Serial No. 341,474.

To all whom, it may concern.-

Be it known that I, JOHN KAUT, a citizen of the United States, residingat St. Louis, State of Missouri, have invented certain new and usefulImprovements in Photographic- Printing Apparatus, of which the followingis a full, clear, and exact description, reference being hadto theaccompanying drawings, forming a part hereof.

My invention has relation to improvements in automatic clock-controlledactuating mechanism for shutters for photographicprmting frames; and itconsists in the novel construction. and arrangement of parts more fullyset forth in the specification and point ed out in the claims.

In the drawings,Figure 1 is a front elevation of my invention. Fig. 2 isa vertical middle longitudinal section. on line 2 2 of Fig. 1, showingthe shutters open. Fig. 3 is a horizontal section on line 3 8 of Fig. 1,with l shutters opei. Fig. t is a similar section with shutters closed.Fig. 5 is a vertical section on line 5 5 of Fig. 3, showing the clockcontrolling mechanism. Fig. 6 is a similar section on line 6 6 of Fig.4; v Fig. 7 is a face view of the clock mechanism with front wall partlybroken away, an d Fig. 8 is a perspective view of a reducing-frame forthe main carrier-frame for holding a smallersized printing-frame.

The present invention is an improvement on the photographic-shutterdevice shown in my United States Patent No. 836,928, of November 27,1906, and has for its object to control the closing movement of theshutters by a clock or time mechanism set to operate for any number ofseconds or minutes of err-- posure of the printing-plate to the light bywhich the printing is effected. in its generic contemplation the presentimprovement does not differ from the patented one,since, likeit,the mainobject is to effect the opening of the shutters for an exposure movementof the printing-frame and toplose the shutters upon conclusion of theprinting operation.

The advantages of the inventionwill be better apparent from a detaileddescription thereof, which is as follows:

Referring to the drawings, 1 represents a box or hood forming the frontextension of the bellows 2, by which the distance of the rearlight-chamber 3 from the printing-frame is regulated. These features arewell known and require no detailed description. The

rear of the box 1 is closed by a translucent or frosted difi'usion-plate4 for subduing in a measure the rays emanating from the electric lamp 5.Hinged along the front upper edge of the box 1 and swinging in avertical plane is a carrier-frame 6, so termed for convenience,sinee itserves to support or carry the printing-frame 7, holding the negativeand sensitized plate or film,) which not only carries theprinting-frame, but may temporarily support a smaller or reducincarrierframe 6, Fig. 8, for holding a smal er printing-frame. The frame6 may in turn support a still smaller reducing-frame, according to thesize of the print required.

The printing-frame is held in position by having its upper memberinserted behind the depending portion of a bent plate or strip 8,secured to the carrier-frame, the upper extension or arni of said platebeing secured to the adjacent end of a contracting spring 9, whoseopposite end is coupled to an eycbolt or post 10, mounted on the box 1.he normal tendehey of the spring 9 is to oscillate or swing thecarrier-frame outwardly, as seen by the dotted position of Fig. 2.Hinged to the sides of the. front of the box 1 are theshu ttcrs or doors11, the free vertical edge of one of the doors being provided with astrip 12 for covering the joint between the shutters when closed, (thisdoor in practice closing a fraction of a second after the oppositedoolj) each door or shutter being coupled near the bottom to theadjacent sides of the carrierframe by means of links 13 13, (the linkconnecting the door with the strip 12 being a trifle, but imperceptibly,longer to allow for the later closing above referred to to give thestrip 12 opportunity to close over the opposite door.)

it is obvious from the foregoing connections that as the frame 6 isswung outwardly under the tension of the spring 9 it will drawtheshuttersto a closed position, and as the frame is forced inwardlytoward the box 1 it will automatically force the shutters to an openposition. T he latter result follows when the printing-frame ispositioned for the printing operation. The operator first inserts theprinting-frame 7 into position behind the terminal extension of thestrip 8, Fig. 2, and forces the carrier-frame 6 inwardly, whereupon theshutters are forced to an open position. to ai'lmit' the light from thelamp 5 to the plate. in being thus forced back the carrier-frame islocked to what may be termed the printing or exposing position by theshouh i l O 1 V 1 nxeo at one one the plttlll) using, Uliu til the letehlruig 9 will with i l e eerteui l 1 role eloeir.

The latch is connected to the outer end of e.rooiproeating intercepting-rod 26, which in its inner movement into theclock has its inner end. shoved in the path ol the arm 16, oscillatingwith the eseepeinent e, and stops the clock mechanism.
